The 'dead' trees are not in the final game, the approach to hyrule castle is different
Hyrule field looks more open, compared to the 4 fields with the castle in the middle that we got in the final game.
Unknown dungeon.
The Ghoma is chasing Link in a forest environment. It ended up as a normal boss in the Temple of Time.
Creature, again unknown.
A beta forest not found in the final game.
Shown when they announced the 'delay' many speculated Nintendo just took some random development shots to show that the game wasn't finished to cover up the move to the Wii.
This is not in the game, not in Zora's Domain or anywhere else. It might've been Lake Hylia but the water level is higher there and the ground is covered in dirt. Might again have something to do with the mysterious river that leads somewhere.
Could be a beta fishing spot.
There was a plan to change camera angles for dungeons, as shown in these screenshots. It turned out to be troublesome so they cut it along with this dungeon.
This tree is not in the game but there's a dead tree somewhere on Hyrule Field that looks alot like it.
These creatures are in the game but not in this location and they're smaller.
Notice how the objects in the game could fall over, like there was some sort of physics system in place that is not in the final game(objects simply break). Also note the chairs which might indicate that A) a designer got lazy filling up the room, B) this location was more than just a dungeon/lair.
Beta Twilight creature
This and other shots fueled speculation that at one point Link could use the boat to travel to different places.
Beta enemy hacked in with AR
Gorons..
GORONATOR!
Again hacked in with the AR
Another Beta hyrule field.
Green Chu Jelly can be obtained in the game...
probably to fill the magic meter that is actually on the back of the PAL box of the shipped game. That must've been cut out at the last minute, maybe it wasn't magic at all but tied to Link's magic sword slashes?
The hauling scenes in the actual games are different and this might've been rendered just for the GDC trailer.
There's a river that leads somewhere. Possibly the Zora province.
Again the river
Beta entrance to Hyrule castle or a bridge? In any case these buildings were demolished and used at various bridges in the final game.
Beta forest with animals outside of the villages. Aonuma stated in an interview that animals would be an important part of the game.
Well hello there Beta dungeon!
Those enemies are found in the game but with a different style.
Seems to indicate that Hyrule was a vast and open landscape and not just a couple of areas connected with bridges and blurred textures.
Evil is approaching, in the final game the evil had already come and gone.
